You mean you only see this with a trackpad/mousepad ?I see this always, with a mouse or with a touchpad... So I'd tend to say it has nothing to do with the input device, but with the mouse cursor display (static image is the "edit" cursor, moving image is the arrow / whereas the image should always be an "edit" cursor inside a text window).

For me, the mouse cursor changes back and forth no matter what input I use.The difference is that the trackpad lags when that happens, sometimes recording input with a few seconds delay. And with my corded logitech mouse, it doesn't affect performance but the icon switching is still there.I actually noticed this too but never reported it since it's not a deal-breaking issue but it would be nice if it got fixed.

now that you mention it, you're right...the cursor keeps changing with a mouse as well but there is not lag like there is with the touchpad.

i really hope this can be fixed. i started using a mouse on my tablet now to avoid the issue but i'd really like to avoid having to drag a mouse with me all the time. after all the idea of a tablet like the surface is mobility;P
